    Pick out the WRONG statement from the following.

    A)  Lateral shift increases as the angle of incidence increases.

    B)  Lateral shift increases as the value of refractive index increases.

    C)  Normal shift decreases as the value of refractive index increases.

    D)  Both normal shift and lateral shift are directly proportional to the thickness of the medium.

    Correct Answer: C

    Solution :

    : Normal shift \[=t\left( 1-\frac{1}{\mu } \right)\] Lateral shift \[=t\sin \,i\left( 1-\frac{\cos i}{\sqrt{{{\mu }^{2}}-{{\sin }^{2}}i}} \right)\]
